Mini Ultra 16 MHz (Arduino Compatible)

Description

We got a lot of request to make a 5 V version of our popular Mini Ultra 8 MHz board that runs at 3.3 V. If you need to operate at 5 V off batteries, this is the board is for you. Works great with our Arduino compatible low power library to allow flexible low power management of the board.

Specifications:

• Compatible with Arduino IDE using “Arduino Pro Mini 5 V 16 MHz” as the board option
• Microcontroller – ATmega328P-AU
• Clock – External ceramic 16 MHz resonator
• Operating voltage – 5.0 V
• Low quiescent current (40 μA) on-board 5.0 V 450 mA boost regulator (with a 4.2 V input power)
• Ultra low power – Minimum 45.0 μA in power down mode (with a 3.6 V input power)
• External DC source range – 2.3 – 5 V:
  • Suitable for battery operation (example: 2×1.5 V batteries, 3.6 V Lithium-Ion/Polymer)
• Indicator LED connected to digital pin 13 through a MOSFET
• FTDI 6-pin header
• Emphasis on low noise design approach:
  • Analog reference voltage with LC filter
  • Digital pins (D0-D13) breakout on 1 side of the board
  • Analog pins (A0-A7) breakout on 1 side of the board:
    • Analog pins A6 & A7 are pure analog input pins only
• 600 mil in between 2 breakout headers – suitable for breadboard usage
• Dimension – 18.41 mm x 39.37 mm (0.725″ x 1.55″)
• RoHS compliant – Yes
